Selection Notes

The 3-pole (X) OXB200E3X2QB keeps the neutral solid between the two sources, which fits installations with a single bonded neutral; specify the 4-pole S variant where the neutral itself has to switch. At 200 A with an 18 kA short-time withstand, it is sized for sub-distribution transfer rather than a main incomer. The Level 2 DIP-switch controller is the base interface in this frame - the Level 3 LCD and Level 4 touchscreen variants add on-site display and event logging. QB termination feeds the supply in at the bottom of the enclosure.
